Problem

Out of the box, if you want to log into Outlook Web App, you need to use the Domain\Username format, like so;

OWA Domain username login format

Seeing as how Microsoft are making a big song and dance about using UPN's to log into Office 365, I thought they might have changed from the NT4 way of doing things, but hey what do I know?

As we all know users are stupid, Domain\Username is up there with string theory and quantum mechanics. So how do you change the format to simply Username?

 

Solution

Log into the Exchange eAdmin Center > Servers > Virtual Directories > Locate OWA > Edit.

OWA Edit Virtual Directory

Authentication Tab > Use Forms Based Authentication > User name only >Browse > Select your domain > OK > OK.

OWA username format copy

Now on the server that's hosting the OWA Website you need to Restart IIS.

iisreset /noforce

IISRESET NOFORCE

Now your users can authenticate with just their username.

OWA username only login

Exchange Admin Center Logon Note

This will also change the login method for the Exchange Admin Center website (ECP). because by default it has this set in it's properties;

Exchange Admin Center ECP username only login
